PAPER BOX.

Specification of Letters Patent.

Patented Apr. 8, 1919.

Application filed January 13, 1917. Serial No. 142,292.

.aims particularly to provide a boxor container in the shape of a gripor satchel which may be formed from a single piece of mate= rial andfolded or creased into, form.

In the accompanying drawings I have illustrated one embodiment of myinvention, although it is to be understood that the invention may appearin other forms.

Figure l is a plan view of the paper blank from which the box structureis formed;

gig. 2 is'an end view of the box set up; an

Fig. 3 is a side view of the box showing in dotted lines the positionoccupied by one of the end flaps while the box is being filled.

In providing a box or container for small quantities of goods,particularly such goods as candy and the like, a neat and attractivecontainer or box is very valuable. The box which I shall describe as anembodiment of my invention takes the form of. a satchel having suitablehandles by which to carry the same, these handles being formed integralwith the walls of the box. The blank from which the box is formedcomprises essentially the bottom portion 1 and the side walls 2 and 3.The end space is closed ofi by means of the end flaps 4 and 5. Handles6' and 7 are formed integral with the side walls 2 and 3, respectively,and a closing flap 8 is formed integral with one of the side walls 3 andis adapted to fold over the upper edge of the opposite side wall 2. Theclosing flap 8 is provided with a tongue 9 which is adapted to enter aslot or slit 10 to hold the closing flap in place. One of the sideportions 2 is provided with tabs or straps 11 and 12 which are suitablyformed to cooperate with the slits 13 and 14 formed in the opposite wall3.

A tight and serviceable box may be made of only the elements which Ihave so far described, but in orderto improve the appearance andoperation of the box, I have provided the flaps 15 and 16 upon the sideportion 2 and the flaps l7 and 18 upon the side portion 3. These flapsare adapted to be folded into the inside of the box and in doing so theytend to keep the corners tightly closed and tend to keep the side wallsfrom bulging out due to the additional strength which they afford. Ihave also provided the end portions with side flaps 19, 20 on the endportion 4: and 21, 22 on the end portion 5. These endflaps like the sideflaps tend to keep the corners of the end walls 4 and 5 straight and toreinforce the same, also tending to make the corners of the box moretight. If it is desired to carry a liquid or semi-liquid substance whichmight leak out of the corners of the box, I form the end flaps integralwith the side flaps providing only a fold between these parts. As thismodification is obvious to those skilled in the art, I have not found itnecessary to illustrate the same. v

I find also that the side flaps 15, 16, 17 and 18 may be dispensedwithand the end flaps retained or vice versa but I find it preferable inmost cases toretain the end flaps in order to strengthen these end flaps4. and 5 and to keep the corners tight.

Folding and filling of the box is accomplished as follows: The sideportions 2 and 3 are folded up on the dotted lines a and b the handles6'and 7 being brought up flat against each. other. At the same time theflap 23 which may be retained for keeping the top tight is folded overon the line 0 upon the inside of the box. The closing flap 9 is thenfolded over on the line b and the tongue 9 is inserted into the slot 10.The flaps 15 and 17 on the side walls 2 and 3 are then folded in on thelines 6 and f. The flaps 19 and 20 upon the end portion 4 are thenfolded on the dotted lines 9 and h and the end portion 1 is folded inupon the dotted line 2' thereby closing off the one end.

The retaining strap 11 is then folded on the dotted line 7' and la andthe tongue 24 of this flap is inserted in the slit 13 in the oppositeside wall thus securely strapping in the top of the end portion 4: ascan be seen in Fig. 2.

At this stage the opposite end of the box is open and the candy, orother material. which is to be inserted is then introduced into the boxand thereafter the flaps 16 and 18 are folded in on the line Z and m andthe flaps 21 and 22 are folded in on the lines a and 0 and the endportion 5 is folded on the line p to close the end of the box. The strap12 is then folded on the lines 9 and 1", and the tongue 25 is insertedin the slit 14: thus completely closing the box. As above explained theflap 23' may be dispensed with.

Similarly the flaps on the side portions and on the end portions may bewholly or partially dispensed with.

What I claim is:

l. A blank for forming a paper box out and scored to form a rectangularbottom portion, rectangular sides joined to the bottom along its sideedges and adapted to be formed up with their free edges in contact toform a box, triangular end portions joined at their bases to the ends ofthe bottom portion, and adapted to be formed up to close the ends of thebox, a handle formed on the outer edge of each side portion, the twohandles being adapted to cooperate to form a complete handle member whenthe sides are formed up with their outer edges in contact, a lockingflap within one handle, and a cooperative slot in the other side member,whereby when the box is formed, said locking flap can embrace the outeredge of the opposite side member to interlock with same to hold the freeedges of the sides together, a locking strap at each end on one of theside members, adjacent to its outer edge and a cooperative slot in theopposite side member at each end for interlockment with said straps,whereby when the box is formed the straps can embrace the tops of theend members and lock the two sides of the box together.

i 2. A paper box comprising a rectangular bottom; portion, rectangularsides joined to the bottom along its side edges with their outer edgescontacting with each other, and said sides extending at an acute angleto each other, triangular shaped end members joined at their bases tothe ends of the bottom portion and closing the ends of the box, integralstraps extending fromv the upper portion of one of the side membersacross the upper ends of the end members, and having their ends ininterlocking engagement with the opposite side member, integral handlesextending from the upper edges of the side members and contacting witheach other, and a flap member within one of said handle membersembracing the upper edge of the opposite side and formed forinterlocking engagement therewith to hold the flap in bent position.

3. In a paper box, two side members having their adjacent edges incontact, and said side members extending at an acute angle to eachother, a tongue integral with one side, bent over the adjacent edge ofthe other side, and the free end of the tongue tucked into a slot in theother side, thereby retaining said flap bent over said edge of theopposite thereby retaining said flap bent overthe edge of the oppositemember and said box closed.

5. A blank for a paper box scored and cut to form a rectangular bottom,rectangular sides having integral handles projecting at their outeredges, a slot within oneof the handles forming a flap, said blank scoredat the junction ofsaid flap with the side adapting the flap to be bentover the outer edge of the opposite side, a projecting tongue on theouter end of the flap, a slot in the opposite side to receive saidtongue, triangular end members for closing the ends of the box, tonguesprojecting from the upper part of one of said sides having lateralprojections at their ends, the opposite side having slots to receivesaid tongues, the projections engaging the ends of said slots, saidtongues beingadapted to embrace the narrow ends of said triangular endmembers to retain the end members in closed position.

6. A triangular shaped paper box having sides extending at an acuteangle to each other and provided with integral handles on theircontacting edges, means within the handles for locking said sidestogether, integral triangular shaped ends for the box, and meansintegral with the box and independent of the lock within the handles forlocking said triangular ends in box closing position.

In witness whereof, I hereunto subscribe my name this 11th day ofJanuary, A. D. 1917.
